Hello,

I was looking for a 1MOhm Digital pot, but I don't seem to find any. Its for a proyect that uses a 1MOhm log pot.

is thre such thing?

Thanks Luis

Luis,

Take a look at Maxim's site

I am sure you can find what you are look for.

not 1 Mega Ohm ones for some reason they tend to get up to 100KOhm

Yes. You are right they max out at 100K. Other than connecting 10 of them in series, I am wondering whether is there a resistance multiplier circuit to make this possible.

However, I found there is one from [Analog Devices] (http://www.analog.com/static/imported-files/data_sheets/AD5241_5242.pdf) with 1M option. Also take a look at this for all digital POTs.

hmmm, might be interesting to find a 10% 1MOhm resistor that was reading a bit low and then use a 10kOhm pot in series... just a thought.
